Definitions

  • the present invention relates to a fixing device for assembly cable trays on their supports.
  • the fixing device is more particularly intended for the assembly of perforated sheet cables.
  • Document FR-A3-2 540 946 discloses a carrier device comprising a cable tray immobilized on a console by means of crampons with two elastic temples. Once in place, these crampons can only be removed with difficulty by inserting a tool in an oblong hole, which is not always possible depending on possibly limited access to these studs.
  • the free ends of the elastic clip are arranged inside the cable tray, on the one hand risking injury electrical cables and secondly to be unhooked by a cable during its installation.
  • the lateral support of the cable tray relative to the support is very random since the free hook-shaped ends of each elastic tie do not are not retained laterally on said cable tray.
  • free ends hang on the upper edge of the walls vertical of the cable tray, preventing it from being closed by example by a cover.
  • the fixing device consists a locking key which comprises an elastically deformable elongated body provided at each end with cooperating fastening means each with one of the corresponding oblong holes in the bottom of the cable tray, said means respectively allowing the retention of the cable tray on a metal support and the locking of the key on the bottom of the cable tray.
  • the lock key comprises between the fixing means a retaining stop which cooperates with an intermediate oblong hole in the cable tray for holding lateral of the elongated body.
  • the distance provided between the fixing means and the stop retainer corresponds substantially to that separating the oblong holes formed at the bottom of the cable tray.
  • Fig. 1 is an exploded perspective view showing the device fixing for the assembly of the corresponding cable tray on its support according to the present invention.
  • Fig. 2 is a top view illustrating the installation of the key lock on the bottom of the cable tray.
  • Fig. 3 is a section along III-III (fig. 2) representing the retention of the cable tray on its support using the key lock.
  • Fig. 4 is a section on IV-IV (fig. 3) showing the first means of fixing the locking key allowing the retention of the cable tray on its metal support.
  • Fig. 5 is a section along V-V (fig. 3) illustrating the stop of retained inside an oblong hole in the cable tray for holding side of the locking key.
  • Fig. 6 is a section along VI-VI (fig. 3) representing the second means of fixing the locking key allowing its retention on the bottom of the cable tray.
  • the fixing device which consists of a locking key 1 produced in an elongated metal body 1 a for fixing a cable tray 2 made of perforated sheet metal on a support 3.
  • the elongated body 1 a of the key 1 comprises at one of its ends a first fixing means in the form of a beak 1 b arranged in a plane substantially perpendicular to that containing said body.
  • the spout 1 b has an outer profile 1 c forming a cam while said spout is pierced in the middle with a hole 1 d in the shape of a C.
  • the body 1a has on the greater part of its length inclined faces 1 e and 1 f of which the surface increases progressively to form adjacent to and on either side of the spout 1b stops 1g and 1h which are will see the function better later.
  • the body 1 a comprises, opposite the spout 1 b, a second fixing means consisting of an inclined face 1 i which is partially cut out to form a tab 1 j .
  • the latter is folded in a direction perpendicular to that of the face 1 i to form a 1 k opening slot whose opening is increasing as a function of the inclination of the tab 1 j .
  • the body 1 a comprises substantially in its middle and more particularly between the spout 1 b and the inclined face 1 i a cut-out constituting an inclined tongue 1 l or retaining stop directed in the same direction as that of said spout relative to the body 1 a .
  • the raceway section 2 includes a bottom 2 is defined by two vertical wings 2 b and 2 c.
  • the bottom 2 a has two parallel and longitudinal ribs 2 d and 2 e .
  • the ribs 2 d and 2 e are also parallel to the wings 2 b and 2 c so as to delimit a space 2 f which is in the same plane as the bottom 2 a .
  • the bottom 2 a and the space 2 f are pierced with a number of oblong holes 2 g regularly spaced and aligned with each other.
  • the bottom 2 a has, between each series of oblong holes 2 g, reinforcement ribs 2 h arranged perpendicular to the holes 2 g and to the ribs 2 d and 2 e .
  • the upper edge 2 i of each vertical wing 2 b and 2 c can be bent towards the outside of the cable tray 2 to allow, for example, the fixing of a cover, not shown.
  • the support 3 on which the cable tray 2 must be fixed is produced in a metal profile having the shape of an ⁇ or a C or a U.
  • the support 3 has a bottom 3 a which is bordered laterally by two inclined side walls 3 b and 3 c whose free ends are folded to form two wings 3 d and 3 e parallel to the bottom 3 a .
  • the bottom 3 a of the support 3 is pierced with oblong holes 3 f between which are inserted holes 3 g with a square section.
  • the support 3 may have a different shape provided that it has a similar base to that described 3 above for the implementation of the invention.
  • the support 3 is arranged perpendicular to the bottom 2 a of the cable tray 2 so that the oblong holes 3 f correspond with those 2 g .
  • each end of the body 1 a and the tongue 11 l is equivalent to that corresponding to the center distance of each oblong hole 2 g provided on the bottom of the cable tray.
  • the spout 1 b , the tongue or retaining stop 1 l and the tab 1 j each cooperate with a different oblong hole 2 g which are directly adjacent to each other.
  • the operator begins to set up the cable tray 2 on its support 3 so that one of the oblong holes 2 g cooperate with that 3 f of the support 3. Then it presents a first key 1 so that its end comprising the spout 1 b penetrates through the holes 2 g and 3 f so that the hole 1 d receives the thickness of the profile forming the bottom 3 a of the support 3 (fig. 3 and 4).
  • the tilting of the key 1 allows the operator to simultaneously introduce the tab 1 j and the tongue or retaining stop 1 l in the other two following holes 2 g in order to permanently lock the key on the bottom 2 a of the path cables 2 (fig. 5, 6).
  • the key 1 is locked by the face 1 i and the lug 1 j which come to sandwich through the slot 1 k the thickness of the bottom 2a at the corresponding opening 2 g (fig. 6).
  • the stopper or tongue 1 l cooperates with the hole 2 g between the first two, that is to say those receiving each end of the key 1 so as to retain laterally the second fixing means consisting of the inclined face 1 i of the leg 1 j , and of the slot 1 k and more particularly of the body 1 a .
  • the distance provided between the external profile of the cam 1 c and the end of the spout 1 b is greater than the width of the oblong hole 3 f in order to avoid any disengagement of the spout 1 b after tilting the key 1.
  • the fixing device allows the assembly of the cable tray 2 on their support 3 by means of the locking key 1 and whatever the configuration of the holes 2 g and 3 f .
  • the cable tray 2 is assembled on its support 3 by through the locking key 1 described above.
  • a second locking key 1 is provided which is mounted either in the same direction, or in opposite direction with respect to the first to distribute clamping forces.
